The LIFF Shortest is a magnetic water conditioner that uses the principles of magnetism to alter the characteristics of hard water. Once conditioned by the Shortest, limescale simply passes through a domestic hot water system without sticking to heat exchange surfaces. The Shortest is able to extend the life of household water appliances when used in hard water areas, such as hot water cylinders, and shower units, while improving the efficiency of your heating system. A more efficient boiler will help reduce your fuel bills and provide lower overall maintenance costs.
